Computational Fluid Dynamics (CFD) is an integral part of the engineering design and analysis process for many companies and research organizations. CFD offers the ability to accurately predict the performance of new designs or processes before they are ever manufactured or implemented. CFD applications work by dividing the region of interest into a large number of cells or control volumes. This is referred to as the "mesh" or "grid". Within each cell, the partial differential equations describing the fluid flow, known as the Navier-Stokes equations, are rewritten as algebraic equations that relate the pressure, velocity, temperature and other variables to the values in the neighboring cells. These equations are then solved numerically yielding a complete picture of the fluid flow down to the resolution of the grid. The resulting image is an accurate depiction of the fluid dynamics surrounding the grid.

PSSC PowerWulf Clusters are custom configured, turn-key solutions that are optimized for CFD applications. Our PowerWulf Clusters are used by several CFD application developers for inhouse testing and development including Metacomp Technologies and Flow Sciences. According to Sukumar Chakravarthy, Metacomp Technologies President, "PSSC keeps tabs on all changes in technology so we don’t have to, including hardware, chip, interconnect and operating system developments."

TURN KEY SOLUTION [back to top]
What do you need out of your Linux Supercomputer? Reliability, performance, ease of use and excellent support are probably on the top of your list. PSSC Labs understands the significance of your work and your need for the most powerful, reliable Linux Supercomputer possible. PowerWulf Clusters are the answer to your Linux Supercomputer needs. PowerWulf Clusters are elegantly configured, easy to use Linux Supercomputer solution that is ready for your use right out of the box.

You will not need to consume valuable time configuring your Linux Supercomputer. Instead PSSC Labs Linux Experts will deliver your supercomputer with CBeST, the Complete Beowulf Software Toolkit. CBeST is much more than just cluster management. CBeST is a detailed process designed to deliver exactly what you need out of your Linux Supercomputer: reliability, performance, ease of use and excellent support. Our industry recognized CBeST software toolkit includes all cluster management tools necessary to manage, monitor, maintain and upgrade your cluster. All PowerWulf Clusters are fully configured with CBeST and thoroughly tested before leaving our facility. Your PowerWulf Cluster includes unlimited liftetime support. We are available to help answer your questions regarding PowerWulf cluster hardware and CBeST software. For complete CBeST details please visit (this will link to the product – software – cbest page)

Before beginning CBeST installation, PSSC Labs Cluster Technicians will work with you to properly configure the network settings, file system configuration and cluster nomenclature. This allows PSSC Labs to deliver the most TURN KEY solution possible.

UNLIMITED LIFETIME SUPPORT [back to top]
All PowerWulf Clusters include unlimited lifetime support at NO additional cost. You are welcome to call or email any question you have regarding cluster hardware and software directly to the PSSC Labs Cluster Technician responsible for configuring your cluster. This ensures that you receive the best possible technical support in an immediate fashion.

PERFORMANCE TUNING [back to top]
PowerWulf Clusters are optimized for maximum performance. Our superior experience allows PSSC Labs Cluster Technicians to tune performance for maximum results. BIOS settings, network configurations, memory configuration, file system and all other possible areas for performance improvement are carefully reviewed and scrutinized. This ensure that each PowerWulf Cluster provide the highest possible computing power. Before any PowerWulf Cluster ships it must pass our internal performance standards.

EXPANDABILITY [back to top]
Easily add more nodes, memory, network interconnects to your PowerWulf cluster. With CBeST software tools expanding the size of your cluster is fast and easy. PSSC Labs Cluster Technicians will be available to help every step of the way at NO additional cost.

FLEXIBILITY [back to top]
PSSC Labs offers the most hardware and software choices available. You can customize your PowerWulf Cluster to meet your needs and budget. Chassis, processor, memory and networking options are all available. Select the operating system, MPI version and file system you need.

STABILITY [back to top]
PSSC Labs testing procedure is considered one of the most stringent in the industry. Each PowerWulf Cluster undergoes a minimum of seven days continuous testing and retesting. For complete testing detail procedures please see below.

  1. Assemble the system, update Bios to latest version, set BIOS to match the rest of the hardware. (approx 1 hour)
  2. Run Memtest to find MEM, CPU or MOBO errors. (approx 1-2 days)
  3. Run STRESS to find MCE errors, (approx 3 days)
  4. Power down, unplug, cool system. (approx 3 hours)
  5. Power up, run Memtest. (approx 1 hour)
  6. Power down, unplug, cool system (approx 3 hours)
  7. Power up, run Memtest. (approx 1 hour)
  8. Power down, unplug, cool system. (approx 3 hours)
  9. Power up, run Memtest. (approx 1 hour)
  10. Power down, unplug, cool system. (approx 3 hours)
  11. Install HPC Linpak and run over entire cluster (approx 3 days)
  12. Install OS of customer choice and run benchmark test (approx 3 days)
  13. Power down, unplug & ship to end user.

Some companies may take testing shortcuts or not test the cluster as a complete solution. Ultimately these shortcuts will cost you a significant amount of time, energy and money. PSSC Labs eliminates all of the headaches through our testing procedure.
